' WRENCH.

' simple, inexpensive, and efiicient wrench of the character describedin which the nut-en- I gaginghead is pivotall mounted foruniverr salmovement on the s ank or handle Wheieby the device may be used formanipulating nuts not accessible with an ordinary wrench. A furtherobject of the invention is to generally improve this .class of devicesso as to add to' their utility and durability as well as to reduce thecost of manufacture.

With these and other objects in view the invention consists in theconstruction and novel combination andarrangement of parts,

2 5 hereinafter fully described, and illustrated in' the accompanyingdrawings, it being understood that various changes in form, proportions,and minor details of construction may be resorted to within the scope ofthe ap- 3o pended claims.

In the accompanying drawings, forming a part of this specification,Figure 1 is a side elevation of acylinder-Wrench constructed inaccordance with my invention. Fig. 2 is a 3 5 longitudinal .sectionalview of the same.

Fig. 3 is a perspectiveview of the severalparts comprising the wrenchdetached;

Similar numerals of reference indicate corresponding parts in all thefigures of the drawpl ings.

'The improved devic'e consists of a handleor shank 5, one end of whichis provided with a transverse enlargement fiilhaving a recess- ,7 formedtherein, while-t e opposite end 5; thereof is bifurcated to form apair-of spaced 7 arms 8, between which is pivotall mounted,

v as by a pin or rivet 9, the reduce extension or tongue 10 of anintermediate section 11. The section 1 1 is formed witha second tongueor extension-12, disposed at right an les to the tongue 10 and pivotallymounte on a pin or bolt 13 between the s aced arms 14 of the head 15.The arms 8 an '14 form sockets for the reception of the ton ues on theinter- Specification of Letters Patent.

' free lateral movement of said head in mani pulating the wrench. Theends of the ton ues 10 and 12 are also preferably inclined or eveled at"19, as are likewise the ends of the arms-8 of the handle 5, so thattheseveral sections com risin the wrench are free to move lateral y witrespect to each other.'

.70 head has a umversal movement there y enabling the wrench to beintroduced into a cavity or recess for operating on a nut which is notaccessible with an ordinary wrench. In operation the headof the Wrenchis introduced within the cylinder and positioned on the nut to beremoved or adjusted, after which a bar orlever is inserted in thetransverse recess in the shank or handle to assist. in rotating'saidhandle in the act of adjusting the nut.

' Attention is called to the fact that the head 15 is detachably securedto the intermediate section, so that said head ma be quickly removed andreplaced by a simi ar headhaving a larger orsmaller nut-receivingsocket, as the-occasion may re uire.

While the wrench 1s especiall designed for I use in connection withthres ing-machine cylinders, it is obvious that the same. may be usedwith equally good results for removing and adj usting1 tire-bolts,railway-"bolts, and for various 0t er pur oses. e

Havin thus descri. 'ed the invention, what I 1.
